(1) Microscopic unicellular marine or freshwater colonial alga having cell walls impregnated with silica
(1) The slime molds are now known to be a mixture of three or four unrelated groups, and the oomycetes are now classified in the Chromista, with the diatoms and brown algae.
(2) Ballistic delivery after impact of diatomaceous clasts obviates the need for glacial transport from hypothesized Pliocene diatomaceous marine rocks in the Wilkes and Pensacola subglacial basins.
(3) Massive, bioturbated terrigenous silty clay and diatomaceous mud dominate sedimentation in the distal ice-shelf environment.
(4) From single-celled algae called diatoms to the story of a man who plants acorns, IDFuel reminds us that inspiration for design is all around us.
(5) Many are planktonic like the diatoms and Sargassum, floating free near the water surface, and being carried along by the surface currents.
(6) A deposit that is similar to chalk is diatomaceous chert.
(7) U2018The bottom appeared light and clear, a waste of firm diatomaceous [algae-skeleton] ooze,u2019 said Piccard.
(8) Although diatoms are universal in fresh and sea water, they achieve greater importance in high-latitude oceanic areas, as well as in some continental margin basins where they form diatomaceous ooze.
(9) Algae, diatoms , dinoflagellates, and photosynthetic bacteria all belong to this group of organisms.
(10) For example, replacement of diatoms with chlorophytes will alter cycling of silica because diatoms require silica and chlorophytes do not.
